/**
 * <pre>
 *  区域 Controller,控制业务流程。
 *  提供包括业务流程校验,业务流程控制。当流程非常复杂时候,请在API和Service之间添加一层Manager。
 *  Controller 对外开放Rest,同时可以做简单流程控制。Manager复杂流程控制。Service数据完整性(事务)。DAO/Mapper持久操作。
 *  流程简单: Controller->Service->DAO
 *  复杂流程: Controller->Manager->Service->DAO
 *  对外流程: Controller->Manager->Service->DAO
 * 					    |->外部服务
 *  <b>uri 规则</b>
 *   uri 名词复数.
 *   列表或分页 : GET /persons
 *   单人信息   : GET /persons/1
 *   新增      : POST /persons
 *   修改      : PUT /persons
 *   删除      : DELETE /persons/1
